WCFA'23 - FKM Guideline Non-Linear
Programme of the Workshop
The course is built in such a way, that no prior knowledge on fatigue analysis is needed. The basic principles
of the common fatigue damage estimation are described in the first day,
while the lectures on vibration fatigue analysis follow in next two days.
In order to better suit the needs of participants and to fit the course to the level of their knowledge,
several variants of the course are provided as shown in the table below.
Topics discussed in individual days follow.
Introduction to Fatigue
This part is covered in variants: Introduction to Fatigue (V1), Complete Course (V3).
